Read displacement is an acutely progressing disease, which is characterized by a change in the anatomical position of the abomasum, filled with gases, liquid their combination, right or left. The aim of the research is to compare the effectiveness of various methods of surgical treatment of left-sided abomasum displacement in cows. Surgical treatment of left-sided displacement of the abomasum by "puncture", "suturing through the paralumbal fossa", and "abdominal midline operation" were used. It was established that abomasum displacement is recorded in 4.39% of cows and first heifers of the surveyed farm. In total, 75 first heifers and 31 cows were operated. It was found that each of the methods had both advantages and disadvantages. Given the advantages and disadvantages of each of the compared methods of treatment, as well as a high incidence of left-sided displacement of the abomasum among the first heifers, it is most advisable to use a puncture method that is simple to perform, quick to implement, low invasive, ensures low recurrence rate and high efficiency. In case of sufficient experience of the doctor and the capabilities of the farm facilities for the surgical treatment of cows and first heifers, treatment by suturing through the paralumbal fossa can be recommended.
